Dear "bristol scout":
The PIPE Here again - and, like my old RC WW I scale buddy Hank Iltzsch did for the Bristol Scout D planset (AMA planset no.328) he did up, that was published in the March & April 1981 AMA magazine issues for its two-issue-long construction article...
...he DID specify using 1/8th inch OD aluminum tubing on the tail surfaces for the outer edges on that magnificent aircraft, as it was originally built.
When a set of flying surfaces actually USED metal tubing (especially IF it's "curved" in any two-dimensional way) for their edges, Hank got me into doing the exact same thing for a scale model of such an aircraft, "way back when" over 25 years ago...and my 1/6th scale Old Rhinebeck Fleet Finch RC Scale model has aluminum tubing on much of its rudder's outline perimeter.
The Bristol Scout C I'm doing up on CAD here at home, as a set of 1/4th sized Giant Scale drawings, will be using 3/32 inch diameter, scale sized aluminum tubing, for its rudder perimeter framing...and I'd bet
that using 1/8th inch OD aluminum tubing for the outline of the stablizer will give the Scout C a very realistic appearance.
And...totally UNlike laminated wood strips,
when used to do such outlines...when aluminum tubing IS used
for the curved perimeter framing, and heat-shrunk fabric covering is used to cover the finished structure - I have yet to see the heat-shrunk fabric "swayback" the open lengths of aluminum tubing, while the same CANNOT be said
for tail surface outlines done up with laminated wood strips, without a bit of gusset-like sheet balsawood bracing within the laminated outline pieces.
Adhering heat-shrunk fabric to a metal tubing outline CAN be done, with a coat of the "smelly" contact cement painted onto the bare tubing before covering begins, as a sort of "Balsarite for metal", for the heat-shrunk fabric coverings' heat activated adhesive to bond onto and stay firmly adhered when finished.
The flying "comma" rudder on my CAD set of 1:4 RC Giant Scale plans for
Kurt Wintgens' Fokker M.5K/MG Eindecker prototype is intended to be entirely done with the proper size of aluminum tubing for its outline piece, and I'm not expecting a single "swayback" area on THAT rudder when it's someday built as part of constructing that historic aircraft in miniature for RC enjoyment.
Sooo...aluminum tubing CAN be used on certain parts of an RC aircraft's structure...it's just that it's BEST used on outline pieces for flying surfaces, where the original design used round metal tubing for the very same thing.
For relatively straight metal tubing "main structure" duties (like all Fokker WW I aircraft fuselages) from full scale designs, but in model form...that's most likely best done with round fiberglass
tubing...but that's a story for another day, OR another "Flying Models" forum thread, here at TheAerodrome !!!
